Nuby's Natural Touch bottles help make bottle feeding a smoother, more natural process. The bottles feature a slow-flow Soft Flex nipple that mimics mom's breast shape and the natural flexing of the nipple when breastfeeding. This design encourages latch-on and eases the transition between breast and bottle. The Soft Flex nipple also has soft nubs on its surface to help massage baby's gums. An anti-colic valve feature was designed into the Soft Flex nipple, helping to prevent ingestion of air, which may cause colic. The slow-flow nipple is ideal for newborns, as it keeps babies from feeding too quickly. Each bottle is graduated in ounces and milliliters for ease when measuring and mixing formula. For an even smoother feeding experience, we've designed our bottles with finger grips on the side, making them easier to hold. Included ortho pacifier follows the curves and natural shape of your baby's mouth for a soothing, comfortable fit. Each bottle holds up to 6 ounces/180 milliliters of liquid. This convenient 3 pack of bottles and nipples will keep parents prepared for feeding time.
